SIZE, WEIGHT AND LOAD
When one vehicle is towing or pulling another vehicle, the drawbar or other connection shall be of sufficient strength to pull all weight towed thereby and shall be fastened to the frame of the towing vehicle in such manner as to prevent sidesway, and in addition to such principal connection there shall be a safety chain which shall be so fastened as to be capable of holding the towed vehicle should the principal connection for any reason fail. ('91 Rev.; Ord. #4247, 8/18/97; ’99 Rev.) [Ref. Iowa Code §321.462]
When one vehicle is towing another the drawbar or other connection shall not exceed fifteen feet from one vehicle to the other except the connection between any two vehicles transporting poles, pipe, machinery, or other objects of structural nature which cannot readily be dismembered.
If the towing vehicle is a motor truck and the towed vehicle is a single trailer with a single point of articulation at the hitch connection, the drawbar or other connection shall not exceed twenty-one feet. The length of the drawbar or other connection shall be measured from the centerline of the hitch assembly on the towing vehicle to the front of the body of the towed vehicle. A vehicle which has a drawbar or other connection which measures between fifteen and twenty-one feet in length shall have at least one yellow reflector visible on each vertical face of the drawbar or other connection, located near the midpoint between the towing and the towed vehicle. A vehicle which has a drawbar or other connection which measures between fifteen and twenty-one feet in length shall have affixed to the rear of the towed vehicle a sign indicating that the vehicle is a towed vehicle.

No passenger-type vehicle shall be operated on any highway with any load carried thereon extending beyond the line of the fenders of the left side of such vehicle nor extending more than six inches beyond the line of the fenders on the right side thereof. Passengers shall not ride on any part of any vehicle unless it is expressly designed either for passenger use or designed for carrying livestock, merchandise, or freight.
The load upon any vehicle operated alone, or the load upon the front vehicle of a combination of vehicles, shall not extend more than three feet beyond the front wheels of such vehicle or the front bumper of such vehicle if it is equipped with such a bumper.
('91 Rev.) [Ref. Iowa Code §321.455, 458]
No vehicle shall be driven or moved on any highway, street, or alley unless such vehicle is so constructed or loaded as to prevent any of its load from dropping, sifting, leaking, or otherwise escaping therefrom, except that sand may be dropped for the purpose of securing traction, or water or other substance may be sprinkled on a roadway in cleaning or maintaining such roadway. [Ref. Iowa Code §321.460]
All trucks, wagons, or other vehicles of whatever kind or nature, used for transporting of sand, gravel, cinders, crushed rock, or other like or similar materials shall be equipped with a box or body to contain such material or materials which said box or body shall be tight or sealed in such a manner that no such material or any portion thereof shall leak or be involuntarily discharged onto any street or public alley within the corporate limits of the City of Waterloo.
No such vehicle equipped as before stated shall be loaded beyond that point where any portion of the load of sand, gravel, cinders, crushed rock, or other like or similar materials, reaches above and beyond a point not less than six inches from the lowest point of the top perimeter of the box or body of said truck, wagon, or other vehicle, unless the entire top of said vehicle box or body shall be covered with canvas, tarpaulin, wood, or other material which said top or other material, shall be firmly lashed or fastened to said box or body to prevent the accidental loss of any portion of said load.
